The Automotive composites Alliance is pushing thermoset plastic composites for a wide variety of applications in hybrid cars, including modules that contain the battery pack, electronic controller and wiring harness. In the US the modules are typically made of several metal stampings which are assembled. Use of composites could reduce the module to two pieces with major savings in weight as well as tooling investment. “Unlike metal, composites don’t conduct electricity, therefore providing an extra safety advantage,” says the Alliance report. “They also won’t corrode and allow integrated airflow cooling in the module’s tunnel, all adding to longer battery life.”
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
